[snook]

have the 2010 spec car. the slipperplatething is "untrue" since assembly.
i have a spare slipperplatething and i have a spare spurgear.
however i never switched to the spares because it was never a problem.
yes the spur slightly disintegrated after the first 2 runs (there were tiny spurgear flakes all over the inside of the body...)
BUT it still runs just fine, and the mesh was never better.
id just get a spare spur incase anything happens, but would not worry about it.
